I have this one running now.
It allows you to run a 6808 (not 68HC08 that's a totally different beast) on RC2014. The 6808 is basically a 6800 but with the separate clock chip etc no longer required, and in fact it will run without an external clock much to my surprise. I hadn't realised that they really did mean "may be attached" for the oscillator pins on the chip so I was most perplexed when it booted without a clock card being present!
At the moment I just have some initial boot test code running but it's ultimately designed to load and run Flex which was to the 6800 world what CP/M was to Z80.
The board need a card with the ROM high (eg Ben's 32K/32K card), and a UART.
